Abstract
A subaortic left ventricular aneurysm in a 21‐year‐old white woman is described. The clinical features were those of moderately severe aortic regurgitation, and the chest x‐ray film showed cardiac enlargement with a bulge on the left heart border. Angiography confirmed the presence of gross aortic regurgitation and revealed an aneurysm behind the aortic root. At surgery, the aneurysm was found to be located below the aortic valve ring and communicated with the left ventricle through an ostium of 2.5 cm. Aortic valve replacement and closure of the aneurysmal ostium were carried out successfully.
